Environment and Development: Conflict and Reconciliation; Environment and Economic Growth; Environment and Public Health

Every major environmental case in India has, at its core, a clash between two legitimate goods: the development that feeds, employs and houses people, and the environment on which their health and future depend. This topic examines how that conflict arises, how law and courts reconcile it, how economists understand the link between environment and growth, and why public health is the point at which environmental harm becomes most visible.

1. Environment and Development: The Nature of the Conflict

Development requires land, water, energy, minerals and the capacity of air and water to absorb waste. Each of these draws on the environment. The conflict is sharpest in four settings.

1. Large projects. Dams, mines, highways, ports and power plants alter landscapes and displace people. The Sardar Sarovar (Narmada) and Tehri dams, and the bauxite mining proposed in the Niyamgiri hills, are the leading Indian examples.
2. Polluting industry. Industries produce employment and revenue, but also effluents and emissions that harm those living nearby, as in the tanneries of Kanpur and Vellore or the copper smelter at Thoothukudi.
3. Urbanisation. Cities expand into wetlands, forests and floodplains, and generate waste faster than they can manage it.
4. Livelihoods of the poor. Many of the poorest people depend directly on forests, rivers and commons. Development that degrades these resources harms them first; conservation that excludes them from those resources harms them as well.

For much of the twentieth century the conflict was framed as a choice: grow now and clean up later. India's position at Stockholm in 1972, that poverty itself is a cause of environmental degradation, showed that the choice was false. Without development there is no escape from poverty; without environmental protection development cannot last.

1.1 Illustrations from Indian experience

The Silent Valley movement in Kerala in the late 1970s and early 1980s opposed a hydroelectric project in one of the last tracts of tropical evergreen forest in the Western Ghats. The project was abandoned and the area declared a national park in 1984, an early instance of ecology prevailing over development. The Narmada litigation went the other way: the Supreme Court allowed the Sardar Sarovar dam to be completed, subject to rehabilitation of those displaced. The Char Dham highway case shows a third outcome, in which the Court permitted road widening in the fragile Himalaya because of defence needs, while imposing safeguards and oversight.

2. Reconciliation: How Law Resolves the Conflict

Indian law reconciles environment and development through a set of principles and mechanisms that work together.

2.1 The principles

• Sustainable development is the master principle: development must be of a kind the environment can sustain (Vellore, 1996; N.D. Jayal, 2004).
• The precautionary principle guards against serious or irreversible harm where science is uncertain, and places the burden of proof on the developer (A.P. Pollution Control Board v. M.V. Nayudu, 1999).
• The polluter pays principle ensures that the cost of environmental harm is borne by the person who causes it rather than by the public (Indian Council for Enviro-Legal Action, 1996).
• Intergenerational equity requires that present development not exhaust resources belonging to future generations (State of Tamil Nadu v. Hind Stone, 1981).
• Proportionality asks whether a restriction on development is suitable, necessary and balanced in relation to the environmental aim it serves.

2.2 The mechanisms

1. Environmental impact assessment before a project is approved (EIA Notification, 2006), with public consultation.
2. Conditions and monitoring: clearances are granted subject to conditions whose breach can lead to suspension or closure.
3. Rehabilitation and resettlement: the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013 requires a social impact assessment and rehabilitation of affected families.
4. Compensatory measures: compensatory afforestation and payment of net present value for diverted forest land; environmental compensation for violations.
5. Siting and zoning: restrictions on industries in ecologically sensitive areas and coastal zones.
6. Cleaner technology: courts have repeatedly required industries to switch fuels or install treatment plants rather than close, as in the Taj Trapezium case (1997).

2.3 The judicial approach

Indian courts have not applied a fixed formula. Where a project is essential and its effects can be managed, they have permitted it with safeguards (Narmada, 2000; Essar Oil, 2004; Char Dham, 2021). Where the harm is serious, repeated or irreversible, they have not hesitated to close industries, however great their economic contribution (Kanpur Tanneries, 1987; Sterlite, 2024).

3. Environment and Economic Growth

3.1 Why markets harm the environment

Economists explain environmental damage through three ideas. The first is externalities: a factory that pollutes a river imposes costs on people downstream that do not appear in its accounts, so it produces more pollution than is socially efficient. A.C. Pigou proposed a tax equal to the external cost (a Pigouvian tax); Ronald Coase argued that, if property rights are clear and bargaining is costless, the parties can negotiate an efficient outcome. The second is the tragedy of the commons (Garrett Hardin, 1968): where a resource is open to all, each user has an incentive to overuse it, and the resource is destroyed. Elinor Ostrom, who received the Nobel Prize in Economics in 2009, showed that communities can and often do manage commons sustainably through their own rules. The third is the failure of national accounts: gross domestic product counts the timber sold from a forest but not the loss of the forest itself.

The polluter pays principle is, in legal terms, the internalisation of externalities. The public trust doctrine and the protection of village commons in cases such as Jagpal Singh (2011) respond to the tragedy of the commons.

3.2 Does growth harm or help the environment?

Two schools of thought answer differently. The limits to growth view, associated with the Club of Rome's report The Limits to Growth (1972), holds that continued growth in population and consumption will eventually exceed the planet's capacity. The Environmental Kuznets Curve hypothesis (Grossman and Krueger, early 1990s) suggests that pollution rises in the early stages of growth and falls once incomes reach a certain level, producing an inverted U-shaped curve. The evidence supports the curve for some local pollutants but not for others, notably carbon dioxide, and critics note that rich countries often reduce pollution by moving polluting industry to poorer ones.

The modern synthesis is green growth: growth that is decoupled from environmental damage, so that output rises while resource use and emissions fall. Its tools include cleaner technology, the circular economy, carbon pricing and natural capital accounting under the UN System of Environmental-Economic Accounting.

3.3 Legal instruments linking environment and growth in India

• Carbon credit trading: the Energy Conservation (Amendment) Act, 2022 and the Carbon Credit Trading Scheme, 2023.
• Green Credit Programme: rules under the EPA (2023) rewarding voluntary environmental actions such as tree plantation and water conservation.
• Extended producer responsibility for plastic, electronic and battery waste, making producers pay for the end-of-life management of their products.
• Corporate social responsibility: Section 135 of the Companies Act, 2013 and Schedule VII, which includes environmental sustainability and ecological balance among permitted activities.
• Business Responsibility and Sustainability Reporting: mandated by SEBI for the largest listed companies, requiring disclosure of environmental performance.
• Net present value and compensatory afforestation: putting a price on forest diverted for development.

4. Environment and Public Health

Public health is where environmental harm becomes measurable in human terms. The World Health Organization estimates that a substantial share of global deaths, of the order of a quarter, is attributable to modifiable environmental factors, and that ambient and household air pollution together cause several million premature deaths each year. For India, with some of the most polluted cities in the world and widespread water contamination, the link is immediate.

4.1 Principal environmental health risks

• Air pollution: particulate matter, nitrogen dioxide, sulphur dioxide and ozone, causing respiratory and cardiovascular disease.
• Unsafe water and sanitation: sewage and industrial effluents causing diarrhoeal disease, and naturally occurring arsenic and fluoride in groundwater.
• Hazardous chemicals and waste: pesticides, heavy metals, bio-medical waste and industrial accidents.
• Noise: hearing loss, sleep disturbance and stress.
• Occupational exposure: asbestos, silica and toxic fumes in mines and factories.
• Climate change: heat waves, vector-borne disease and food insecurity.

4.2 The constitutional and legal framework

Article 47 directs the State to regard the improvement of public health as among its primary duties, and the Supreme Court has read the right to health into Article 21. In Vincent Panikurlangara v. Union of India, (1987) 2 SCC 165, the Court held that maintenance and improvement of public health is the duty of the State and is basic to the right to life. The statutory framework includes the Air and Water Acts, the Noise Rules, the Bio-Medical Waste Management Rules, 2016, the Insecticides Act, 1968, the Food Safety and Standards Act, 2006, the Cigarettes and Other Tobacco Products Act, 2003, and the public nuisance provisions of the BNS and BNSS.

Air pollution in Delhi has produced the most sustained body of public health litigation. In M.C. Mehta v. Union of India (vehicular pollution) the Supreme Court directed in 1998 that Delhi's public transport buses switch to compressed natural gas, and enforced the direction in 2002, producing a measurable improvement in air quality. Later orders have dealt with firecrackers (Arjun Gopal v. Union of India, 2017 and 2018), stubble burning in neighbouring States, and the phasing out of old vehicles.

5. Bringing the Three Themes Together

The three themes of this topic are one argument seen from different sides. Development that ignores the environment imposes costs that markets do not count, and those costs appear, sooner or later, as disease and death. Public health is therefore the most persuasive reason for environmental regulation, and economics explains why regulation is needed. The law's task is to make those hidden costs visible and to allocate them fairly, through sustainable development, the polluter pays principle and the right to life.
